CHAQ2020 - Hope Bay - Photographic data - CHAQ2020 - Hope Bay - Orthophotos

The first Swedish Antarctic Expedition (1901-1903), led by Otto Nordenskjöld, sailed to Antarctica on the ship Antarctic captained by CA Larsen, and established a research station on Snow Hill Island. There six members overwintered and performed paleontological, meteorological, geomagnetic and geological studies, while the rest of the expedition set sail for South Orkney.

After the winter, on the way back to Snow Hill Island, the Antarctic got stuck in the ice and sank. At this point, the expedition members were divided into three groups. One of these overwintered an extra year on Snow Hill Island, whereas the other two groups were forced to build stone huts in order to overwinter at Hope Bay and Paulet Island. An Argentinean vessel, the Corbeta Uruguay, rescued the expedition in November 1903.

CHAQ 2020 is an Argentinean-Swedish project with fieldwork in the area around the Antarctic Peninsula aiming to investigating and documenting the historical remains of the first Swedish South Polar expedition under the leadership of Otto Nordenskjöld 1901-1903. The material was collected in January and February 2020.

This catalogue entry collects the photographic material and the panoramas from Hope Bay.

The high resolution orthophotos of the shelter (1 mm per pixel) were created with Agisoft Metashape and structure-from-motion photography taken with a Fujifilm X-T2 camera on January 31, 2020. The photos for the high resolution orthophoto of the site Base Esperanza (10 mm per pixel) were taken with a DJI Phantom 4 drone at 150 meters height on January 31 2020, and then processed in Agisoft Metashape.

1901-1903年的首届瑞典南极考察队（First Swedish Antarctic Expedition）由奥托·诺登舍尔德（Otto Nordenskjöld）带队，乘坐由CA·拉森（CA Larsen）担任船长的“南极号”（Antarctic）帆船前往南极大陆，并在雪丘岛（Snow Hill Island）建立了考察站。六名队员在此越冬并开展古生物学、气象学、地磁学与地质学研究，其余考察队员则启航前往南奥克尼（South Orkney）。

越冬结束后，“南极号”在返回雪丘岛的途中被困冰层并沉没。此时考察队员被分为三组：其中一组在雪丘岛额外越冬一年，另外两组则被迫搭建石屋，分别在希望湾（Hope Bay）和波莱特岛（Paulet Island）越冬。1903年11月，阿根廷“乌拉圭号”护卫舰（Corbeta Uruguay）将全体考察队员营救。

CHAQ 2020是一项阿根廷-瑞典联合项目，其野外工作覆盖南极半岛周边区域，旨在调查并记录1901-1903年由奥托·诺登舍尔德带队的首届瑞典南极考察队的历史遗存。相关实地资料于2020年1月至2月间采集完成。

本目录收录了来自希望湾的影像资料与全景照片。

2020年1月31日，研究人员使用富士X-T2（Fujifilm X-T2）相机，通过运动恢复结构（structure-from-motion）摄影技术结合Agisoft Metashape软件，生成了该掩体的高分辨率正射影像图（分辨率为1像素/毫米）。2020年1月31日，研究人员使用大疆精灵4（DJI Phantom 4）无人机在150米高度拍摄了埃斯佩兰萨基地（Base Esperanza）的高分辨率正射影像图（分辨率为10像素/毫米），并通过Agisoft Metashape软件完成后期处理。
